QlikView 11 for Developers

Overview of this book

Business Intelligence technologies are a must-have in every business to make informed decisions and keep up-to speed with the ever-evolving markets. QlikView's disruptive technology makes it a key player and leader in the industry; with its flexibility and powerful analytics environment, building QlikView apps can be mastered by both, business users as well as developers. This book will help you learn QlikView Development from a basic to a practitioner level using a step-by-step approach in a practical environment, and apply proven best practices on each topic. Throughout the book, we will build a QlikView app based on real data about Airline Operations that will help "HighCloud Airlines" make informed business decisions and analysis-guided strategies. HighCloud Airlines executives are evaluating if entering the US market is a good strategy and, if so, which line of business should they focus their investments on; they need QlikView to make the best decision. The application will be evolving chapter by chapter, along with your skills, going from a simple proof of concept to creating a Data Model, adding a custom style, building a Dashboard and handling and manipulating the source data via script. We will meet the "HighCloud Airlines" requirement by using many different data visualization objects and time-saving techniques. The whole application uses real data taken from the Bureau of Transportations statistics of the US and encompasses the operations of Airlines both domestic and international. With three years worth of data, you will help HighCloud Airlines discover where people travel the most, which are the Carriers with the most market share, what is the average load factor per airline, which aircraft is the most used to perform flights, which are the busiest airports, and a whole universe of new insights.

Data architecture


Now that we have a decent amount of QlikView development experience under our belt, we will introduce the concept of data architecture. This refers to the process of structuring the different layers of data processing that exist between the source tables and the final document(s). Having a well-designed data architecture will greatly simplify the administration of the QlikView deployment. It also makes the QlikView solution scalable when new applications need to be developed and when the QlikView environment grows. There can be a lot of different data architectures, but in this section we will discuss two of the most commonly used in QlikView enterprise deployments.

Two-stage architecture

The following diagram depicts the two-stage architecture:

The two-stage architecture is composed of the following layers:

  • Source Layer: composed of the source databases and original tables.

  • Extract Layer: composed of QlikView documents, containing mainly script. These are used to pull the...
